Memot District (Khmer: ស្រុកមេមត់) is a district (srok) located in Tbong Khmum Province, Cambodia. The district capital is Memot town located around 80 kilometres (50 mi) east of the provincial capital of Kampong Cham by road. Memot is a border district and the city of Tây Ninh in Vietnam is around 80 kilometres (50 mi) away by road.
The district is easily accessed by road from Kampong Cham or Kratié. Though there are numerous smaller roads within the district that cross the border into Vietnam, there is no official international border crossing within the district. The closest official crossing is 44 kilometres (27 mi) south east of the district capital at Trapeang Phlong in Ponhea Kraek District. Memot town lies on National Highway 7 near the midpoint between Kampong Cham and Kratié.
Memot district is the most easterly district in Tbong Khmum Province and shares a border with Vietnam. Reading from the north clockwise, Memot shares a border with Preaek Prasab and Snuol districts of Kratié Province to the north. The eastern border of the district is shared with the Vietnamese Province of Bình Phước, while Tây Ninh Province of Vietnam is to the south. The western border of the district abuts Ponhea Kraek and Dambae districts of Tbong Khmum province.
Memot has given its name to a prehistoric culture that lived in the area some 2500 years ago. The Memotian culture is the name given to a series of archaeological sites found in Memot and across the border in Vietnam. The district is home to a number of prehistoric sites which have only recently been studied. In 1959, French archaeologist Louis Malleret first described a series of 17 circular earthworks, each with an outer wall and an inner ditch. He reported this new category of prehistoric sites in the red soil region east of the Mekong in what was then part of Kampong Cham Province and in Vietnam. In 1962, Bernard Philippe Groslier carried out excavations in a circular earthwork near Memot, later called the Groslier site, and named this civilisation "Mimotien". To date 36 of these massive prehistoric villages have been discovered in Cambodia. Radiocarbon dating of fragments of glass bangles found at one site gives evidence for a 1st millennium B.C. date. In 2010 another site, "Samrong Circular Earthwork", was unintentionally destroyed by bulldozers to make way for low-cost housing. 
The Memot district governor is Mr. Cheng Bunnara. He reports to His Excellency, the Governor of Tbong Khmum. The following table shows the villages of Memot district by commune.
